Cyberduck is a libre server and cloud storage browser for Mac and Windows with support for FTP, SFTP, WebDAV, Amazon S3, OpenStack Swift, Backblaze B2, Microsoft Azure & OneDrive, Google Drive and Dropbox.
It's free to use, but will alert to remind you to buy the app constantly.
I usually use the SFTP function to transfer files between my computers and servers.
It supports transfer files between 2 remote servers without first downloading files to the computer Cyberduck is running on.
